Wish to contribute? Great. Please review the following guidelines carefully and always search for existing issues before opening a new one. More time spent managing issues means less time spent improving DevDocs.
Use the [Trello board](https://trello.com/b/6BmTulfx/devdocs-documentation) where everyone can vote and contributors can get a feel for what is most wished for.
1. Search for existing issues; someone may already be working on a similar feature.
2. Before embarking on any significant pull request, please open an issue describing the changes you intend to make. Otherwise you risk spending a lot of time working on something that I may not want to merge. This also tells other contributors that you're working on the feature.
3. Follow the [coding conventions](#coding-conventions).
4. If you're modifying the Ruby code, include tests and ensure they pass.
5. Try to keep your pull request small and simple.
6. When it makes sense, squash your commits into a single commit.
7. Describe all your changes in the commit message and/or pull request.
**Important:** in order to keep things fast and manageable, only the documentation of popular open source projects will be accepted into DevDocs. As more projects find their way in, the required level of popularity will gradually decrease. Additionally, the documentation's license must permit alteration, redistribution, and commercial use of the work. Software vendors that wish to add commercial software documentation to DevDocs may contact me privately.
**Please open an issue before adding any new documentation.**
In addition to the [guidelines for contributing code](#contributing-code-and-features), the following guidelines apply to pull requests that add a new documentation:
* Your documentation must come with a clean and official icon, in both 1x and 2x resolutions (16x16 and 32x32 pixels). This is important because icons are the only thing differentiating search results inside the app. If a project doesn't have an official icon, it won't be accepted into DevDocs. Sorry.
* DevDocs favors quality over quantity. Your documentation should only include API/reference documents that most developers may wish to read semi-regularly. By reducing the number of entries we make it easier to find other, more relevant entries. _(Note: you're more than welcome to submit pull requests removing seldom-used entries from existing documentations.)_
* Try to remove as much content and HTML markup as possible, particularly content which isn't associated with any entries (e.g. introduction, changelog, etc.).
* Names must be as short as possible and unique across the documentation.
* The number of types (categories) must be less than 50.
Please do not submit a pull request updating the version number of a documentation unless you have verified that it can be generated properly using the current code. Because the source will have changed, the code will likely need a few tweaks.
To ask that an existing documentation be updated, please use the [Trello board](https://trello.com/b/6BmTulfx/devdocs-documentation) or the [mailing list](https://groups.google.com/d/forum/devdocs).
* **Improve words and sentences.** English isn't my first language so if you notice grammatical or usage errors, feel free to submit a pull request — it'll be much appreciated. (Note: American English is the preferred form)
* **Participate in the issue tracker.** Your opinion matters — feel free to add comments to existing issues. You're also welcome to participate to the [mailing list](https://groups.google.com/d/forum/devdocs).
